A method for improving the estimation of an existence probability of objects. The objects are detected using sensors installed in a vehicle and/or an infrastructure component. Each tracker of a sensor and/or a sensor group estimates a status of an object and its existence probability using a detection probability model. The detected objects are merged in a fusion list, and each object is assigned a state and an existence probability. Each object of the fusion list is assigned existence probabilities. Each object of the fusion list is assigned additional information indicating which sensor and/or which sensor group has/have detected the respective object in the last measuring cycle. At least sensor-specific and/or sensor-group-specific existence probabilities of fused existence probabilities and the sensor detection probability are compared in a crosscheck, and false negative cases and false positive cases are ascertained for each sensor and/or sensor groups.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method as recited in claim 1, wherein false negative cases or false positive cases assigned to each object are stored, in a manner specific to the sensor or the sensor group, in a false negative list or a false positive list as a function of the position of the object in the fusion list.
3. The method as recited in claim 1, wherein in the crosscheck according to step e), the following are compared to one another: the sensor-specific or sensor-group-specific existence probabilities, additional information of the sensor or the sensor group, fused existence probabilities, and the sensor detection probabilities.
4. The method as recited in claim 1, wherein after cycling through the method steps a) through g), a number of false negative cases and a number of false positive cases is reduced.
5. The method as recited in claim 1, wherein through consideration of the false negative cases and false positive cases fed back via the at least one feedback branch to the detection probability model and the clutter probability model, a first assumption of an existence probability of an object is transformed into a more accurate assumption of the existence probability.
6. The method as recited in claim 1, wherein an accuracy of an assumed detection probability of a first sensor is improved by sensor-specific false negative cases or false positive cases for the first sensor.
7. The method as recited in claim 1, wherein an accuracy of an assumed detection probability of a first sensor group is improved by sensor-group-specific false negative cases or false positive cases for the first sensor group.
8. The method as recited in claim 1, wherein the method improves an accuracy of the modeling of existence probabilities of objects detected by the sensors and/or the sensor groups.
